How can data manipulation operations be performed on multiple variables within an array in PHP?

To perform data manipulation operations on multiple variables within an array in PHP, you can use a loop to iterate through the array and apply the desired operations to each variable individually. By accessing each variable within the array using its index, you can modify its value as needed. 

<?php
// Sample array with multiple variables
$array = [10, 20, 30, 40, 50];

// Loop through the array and double each variable
foreach ($array as $key => $value) {
    $array[$key] = $value * 2;
}

// Output the modified array
print_r($array);
?>
